LM285D-2.5G

Overview

The LM285D-2.5G is a micropower two-terminal bandgap voltage reference diode manufactured by onsemi. It provides a fixed output voltage of 2.5V with an initial tolerance of ±1.5%. The device operates within a temperature range of -40°C to +85°C and utilizes a SOIC-8 surface-mount package. Key electrical characteristics include a maximum temperature coefficient of 80ppm/°C, a minimum shunt current of 20μA, and a maximum shunt current of 30mA. The dynamic impedance is specified at 1.0Ω.

Feature Summary

Utilizes a shunt reference topology for stable operation across varying supply voltages.
Features exceptionally low dynamic impedance and low noise for precision applications.
Designed for extended battery life in micropower circuitry due to extremely low operating current.

Applications

Analog-to-digital converter (ADC) reference sources
Portable instrumentation power supplies
Micropower regulator circuits

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the SOIC-8 package variant matches the required PCB footprint. Confirm that the 2.5V output voltage aligns with the system design requirements before procurement.

Selection Notes

Select this component when a precise, low-power shunt voltage reference is required in a compact surface-mount form factor. The 2.5V output is suitable for driving ADCs or DACs where stability over temperature is critical. Consider the 80ppm/°C temperature coefficient for environmental variations and ensure the operating current remains within the 20μA to 30mA range for optimal regulation.

Part Context

This part belongs to the LM285/LM385 series of micropower voltage reference diodes. These devices are designed for applications requiring tight voltage tolerances achieved through on-chip trimming. The series offers stable operation over time and temperature, making them suitable for general-purpose analog circuitry where reliability and low power consumption are prioritized.
